Chur–Arosa railway line

The Chur–Arosa railway line, also called the Arosabahn, Arosalinie, Aroserbahn or Aroserlinie (all meaning Arosa railway or line), is a Swiss metre-gauge railway line, which is owned and operated by the Rhaetian Railway (German: Rhätische Bahn; RhB). It was built in 1914 by the Chur-Arosa-Bahn (lit. 'Chur-Arosa Railway'; ChA) to connect the Grisons capital, Chur, with the spa town of Arosa. Since 1942, it has been integrated into the network of the Rhaetian Railway. The name of the former company is still used as a name for the line.
